Pt580 Nice Radios. I have one.. It might show up on Ebay some day - If they let me :_)

I doubt that you will get an answer from him since he only made two posts to the forum back in 2021.

You can program Part 95 certified radios to listen on the repeater input frequencies too. I have found that I had to use programming software to do this. I have our GMRS repeater input set to memory on my base radio and a few hand held radios. I have done it with my Wouxun radios using the Won software and with the RT Systems software. Setting a radio to one of the repeater channels and hitting the tone scan will only scan for the repeater output tone. If someone goes through the trouble to program a repeater's input frequency and scans for the input tone just so they can be an ID10T is a total Richard Cranium move in my book.

Yes and no. The NX-5000 radios come with DES 4 key option out of the box, and those keys are software loaded. DMR Enhanced Encryption (ARC4) is an add on, but those are also software loaded. If you want AES, or more than 4 DES keys, you need the AE31k crypo module, then AES & DES are loaded via either hardware keyloader, or KPG-AE1 software. NX-3000 don't have anything out of the box. DMR EE is same as 5000, add on + software load. AES/DES need crypto and hardware or KPG-AE1 software. Kenwood VP8000 & VM8000 are entitlement based encryption, hardware is in the radio by default. AES/DES is keyloader or KPG-AE1, EE can either be done in programming software, or loaded via keyloader. I did have an issue with hardware loaded EE keys though.

Shaw was 100.0 TX only. Is it different now?

I downloaded the CPS from the Baofeng website. The issue isn't the computer or my operating system. The CPS doesn't allow a COM Port to be picked so it can't connect with the radio. I've had no problems programming my other radios so that wouldn't be an issue either. I enjoy setting up radios and have spent hours doing so. You've got to be able to connect to the radio to do anything and without that you're dead in the water. I loaded the CPS for the RT-4D, opened it and can select COM5 so I'll be able to connect to it when it gets here. I'm not doing any Firmware upgrades or switching to Open GD77, I'll run what came on the radio and be happy with it.

Exactly. But I believe that getting permission is the courteous thing to do. So, to summarize, if someone uses your repeater without permission, that’s not a rule violation. Repeater owners are responsible for ensuring that people who use their repeater obey the regulations. Repeater owners must find a way to deny access to someone who violates regulations while using their repeater. Repeater owners are in a tight spot.

Right, nothing prevents a person from listening on the input frequency for the input tones. Of course it’s easier with an opened up radio than it is with a 95E certified radio.

That's true. However a number of people on this forum also hold Part 90 licenses where it is legal. Unfortunately I'm not one of the lucky ones who qualify under the FCC rules to get one. Not exactly a topic for Ham or GMRS, but legitimate for the proper service. Don't forget that a fair number of commercial grade radios already have encryption built in. Just can't use it on Ham and GMRS. Of course when the SHTF, and government reg's are out the window, encryption might be the one thing that will save your butt from those that want you and or your stuff.

That makes it easy. One other forum member has some Kenwood NX5000's and he needs an external hardware key loader. The keys are store in a computer file, I believe, in an encrypted format for security. That's all handled by the key loader software. Many of my older Kenwood digital radios have an option board access port on the back side for plunging voice scramblers and digital encryption options. I've also found some info on the add on encryption used my some of the Kenwood radios in case anyone has an interest. I also have the hardware manual for a third party Voice Inversion Scrambler with Midian’s Kryptic Signaling with the schematic.

Since you know that its not legal on gmrs, then why are you using it there? Sent from my SM-S911U1 using Tapatalk

Encryption is not allowed in the USA amateur service. Businesses licensed in the business band are allowed Encryption. Sent from my SM-S911U1 using Tapatalk

You cannot use the repeater input frequencies unless you are wanting to access a repeater. So. You are deliberately interfering with or trespassing on a repeater if you access it. Now....if you are on the repeater *output * frequency, talking simplex, then you are good. The fcc has taken action against those who have been banned from (ham) repeaters. Usually, a single notice of violation is enough to keep the offending party off the repeater. Sent from my SM-S911U1 using Tapatalk

I've never had it happen, but I only just now posted my repeater as "open" so it's possible. I've been listening to all the repeaters in my area for months, though, and I haven't heard anyone being abusive, so I decided to risk it.

Have you tried to talk to anyone on that repeater? Just because you can open up a repeater does not mean you have a strong enough signal for others to hear you clearly. We have one guy that uses a hand held radio connected to a 6 inch Midland MXTA51 antenna mounted in the center of his Cherokee roof. He can often open the repeater but his signal is not strong enough for us to actually hear him.

I drove around the block and it still would not work at that distance. The HT can talk to the Midland mobile however. So it receives just fine. But the HT is not hearing the Tx from the mobile even at distance. Midland is researching the problem with their engineers now.

The encryption is AES256, providing the radio has the entitlement. I do not need anything special to load the key into my XPR5550e and XPR7550e radios. I just enter the encryption key with the CPS. The key I have to use is well over and I mean alot well, over 50 characters.

Yes, all you need to do is disallow them use and you are done. After that the illegality is on the person who shouldn't be using the repeater. Maybe not illegality but regulatory, less harsh a word.

Shaw Butte is still on the air, at least it is IDing. Either the Station is not repeating or the input tone has changed. The input tone Towers 600 has also changed. Towers 575 appears to be back on the air for now.

Pretty sure they won't. Seems they are interested in the big boyz such as commercial broadcast and emergency use radio being abused by people not allowed on those frequencies. Otherwise they'd be one hell of a busy agency cracking down on all sorts of things like non use of IDing, wrong use of part ?? radios on part ?? use only bands etc.

One way to keep others from using your repeater is to use different input and output tones. Radios will only scan the output tones of other repeaters/radios. But even that is not fool proof. We all know you can't stop someone from using a frequency/channel as no one owns them. Using different tones and/or shutting your repeaters down when you are not using them helps keep others from using your repeater. Our club has sent out cease and desist letters in the past. Knock on wood, those letters has kept most ID10T's from using our repeaters. One particular ID10T has been told to stay off just about every area 2m and 70cm repeater in the area. He has received letters from at least 3 repeater owners. Again this is not fool proof either. A person would have to aggressively cause interference/jamming your repeaters before the FCC will even think about looking into the issue. And good luck getting the FCC to actually do anything about it.

With radios capable of scanning for and picking up tones, there's literally no way to keep someone off your repeater unless you just keep it a secret. I can't imagine FCC or anyone else would consider you responsible if you've taken appropriate steps to notify someone they're not allowed to use it.

I know that, but as you say, it's good to put it out for people to see. It would be extremely bad form to add a repeater you don't own.

Then it seems like you already had the official answer to this question. The FCC does not require a person to seek permission before using a repeater.

I personally filed a complaint a few years ago. They told me it wasn't a rule violation unless the person was transmitting in such a way that they were causing harmful interference. No such harmful interference was occurring, so the FCC opted not to take any action. They told me that it was up to me to resolve any access control issues. That's the very reason why the two repeaters located at my house are always off unless I plan on using them specifically. I got tired of a troublemaker causing problems for me.
